Knowledge workers are the critical mass of people throughout an organization who hold the mental models of how and why things are done as they are as well as how and why to change them. Given that the retention of these workers is a key concern to organizations in every industry, what can be done about worker retention? This paper presents a diagnostic instrument, the Salient Beliefs Review: Individual Well-Being and Organizational Performance Indicators (SBR). The SBR is used to assess the potential for worker satisfaction with an organization. The theoretical background of this instrument develops the concept that the greater the congruence between the outstanding beliefs of the individual and the policies and practices of the organization, the more likely that the individual and the organization will thrive. The SBR was developed to assess the degree of congruence among individuals' beliefs; their own behaviors; their perceptions of the organization's policies; and their perceptions of the organization's practices on seven dimensions. The results of an administration of the SBR to a group of administrators in a suburban school district are discussed. Suggestions for further use of the instrument are also included. (MKA)
